Minimal reproducible full config

-- | Fetches Lazy if not present.
local function bootstrap_lazy()
	local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
	if not vim.loop.fs_stat(lazypath) then
		vim.fn.system({
			"git",
			"clone",
			"--filter=blob:none",
			"https://github.com/folke/lazy.nvim.git",
			"--branch=stable",
			lazypath,
		})
	end
	vim.opt.rtp:prepend(lazypath)
end
bootstrap_lazy()

require("lazy").setup({
	{
		"hrsh7th/nvim-cmp",
		dependencies = { "hrsh7th/cmp-buffer" },
		config = function()
			local cmp = require("cmp")
			cmp.setup({ sources = cmp.config.sources({ { name = "buffer" } }) })
		end,
	},
})

vim.keymap.set("n", "<space>c", function()
	vim.api.nvim_cmd({ cmd = "CmpStatus" }, {})
end)

Description

CmpStatus is not displayed fully when run inside a keymap. The user needs to press enter to get the status fed to them.

Steps to reproduce

1. Open a file with Neovim, e.g., nvim .config/nvim/init.lua.
2. Press <space>c

Expected behavior

Selecting CmpStatus in Legendary runs the command and displays the full status:

Actual behavior

You need to press enter 3-4 times to get the full output of CmpStatus, line by line.

Additional context

This is not a bug in cmp, but a specify in nvim_echo.
The following can be reproduced regardless of cmp.

vim.keymap.set('n', '<Space>c', function()
  for _ = 1, 10 do
    vim.api.nvim_echo({ { 'hi\n', 'Normal' } }, false, {})
  end
end)

Huh, thanks @uga-rosa.

I found neovim/neovim#22478, which, when completed, should address this issue in nvim-cmp.
